IMPROVEMENT IN HANDLES FOR CRQSSCUT-SAWS.

Specification forming part of Letters Patent No. 162,022, dated April13, 1875; application filed January 30, 1875.

T o all whom it may concern:

Be it known that I, WILLIAM J. BoYNToN, of Battle Greek, in the countyof Calhoun and State of Michigan, have invented an Improvement inHandles for GrosseutSaWs, of which the following is a specification:

The nature of my invention relates to an improvement in adjustable anddetachable handles for crosseut-saws; and consists in the peculiarconstruction and combination, with a handle provided with ascrew-threaded tang, of a clip and hooked nut, which grasp the edges ofthe saw-blade, which is clamped to the handle by rotating the latter, asmore fully hereinafter set forth.

Figure l is a perspective View of my improved saw-handle. Fig. 2 is asectional elevation of the same.

In the drawing, A represents a wooden handle, in which there is securedan iron rod or tang, B, projecting from its lower end through a metalferrule, a., the said tang being screwthreaded at its lower end, toreceive a nut, C, having one flat side, which terminates in a hook, b,to engage with the lower edge of the saw-blade. D is an oval clip-platesleeved on the tang above the nut, with one or more ribs, c, on one sideot' the hole. rIhere is a sleeve Cast 0n its back around the opening,which sleeve passes up into the handle through the hole in the ferrule.The saw is inserted between the tang and the ribs c under the plate C,and by rotating the handle the nut is moved up the screw-tang, and thesaw is thus clamped firmly in place. A turn or two of the handle to theleft loosens the nut, and permits the handle to be removed.

What I elaim as my invention is- The nut C having the hook b, and theelippla-te D having the rib c, in combination with the screw-tang B,handle A, and ferrule a, oonstructed and arranged substantially asdescribed and shown.

WILLIAM J. BOYNTON.
